Bearing Supports for Transmissions and Rear Axle Drives

A Systematic Approach

Schaeffler offers system solutions for all the bearings used in a transmission system – space-saving, low-friction and capable of handling high loads. This also includes solutions for radial and axial bearing supports of transmission shafts and gears, as well as complete planetary gear sets. When devising solutions, we look beyond the individual bearing, as we understand and consider the entire system. Conventional tapered roller bearings are being replaced by tandem angular contact ball bearings with two different pitch circles that are designed to support pinions and differentials in the front and rear axle drives. Less friction, and therefore reduced heat buildup, results in significantly higher efficiency which in turn leads to improved fuel economy. This allows modern cars to lower exhaust emissions and consume less fuel, while extending the service life of the individual components.
